Application niermann s,

.-Be it known that I, ZIMRY T; BELL, a citizen of the United States, residing at San Bernardino', in the county of San Bernardino 'and State of California, have invented new and usefullm rovements in Smudging Apparatus for Orc ards, of which the followlng is a specification.

This invention relates to improvementsin smudging apparatus for orchards, 'and it is an object of-the invention to provide a systemb which warm products may be ldelivere among .trees and plants for preventing the action of frost thereon.

t' is also an object of the invention to provide an' apparatus having a system ofdischarge pipes l'and a heat generatin means, the apparatus being also provideh with means for driving the heat products therefrom through the said system of lpip'- ing for discharge among trees or plants which are to be protected from frost.

' leading therefrom, 7 a main branching from casing of a stove or furnace. is to;be located outdoors it is usually made It is a further object'of the inventionfto provide a smudging systeml for orchards in which products of combustion froni-; heater or furnace' may be vdistributed among the trees of the orchard.

In the accompanying drawing forming a part of this specification, Figure 1 is a plan view showing the improved smudging apparatus, the extension `of the pipe system thereof through an orchard being disclosed in diagrammatical form. Fig. 2' is a side elevation of a heater employed in the system and showing a blower connected there with. Fig. 3 is an enlarged detail perspective view of a form of' nozzle which maybe employed inv discharging the heating roducts within the orchard. Fig. 4 is a etail sectional view` through the said nozzle takenupon the line 4 4 of Fig. 3.

The details andfeatures of the invention will now be more particularly described, reference being had to the said drawing in which- 5 indicates a heater, 6 a discharge pipe said discharge pipe, and 8ypipes leading into an orchard and among vegetation which it is desired to protect from frost.

The heater 5 may be of ordinary construction but is generally formed like the If the heaterv of brick and is formed with a combustion chamber 9 therein above an ordinary grate,

as for instance 10, indicated in dotted lines 1n Fig. 2.A A. door 11 is provided in the event that fuel is to be placed upon the said grate. The furnace or heater is also preferably provided with an oil burner 12 eX-.

tending into the same belowthe grate so that oil may beemployed as a fuel instead of woodpcoal or the like.

The upper portion of the heater is preferablycontracted toward a smoke flue 13, which usually extends `upwardlyfrom the furnace from the central -partof the top. The damper 1,4 is preferablymounted at the 'base of the smoke flue j which is generallyv enlarged to receive the same as shown in FigsQjand 2and a lever 15' isconnected .'therewith,'l1aving v.a rod'mor chain 16, del pending therefrom by which thedamper can .be operated. 'From a point near the Atop of the furnace also' the discharge pipe for the heatedfproducts of combustion passes from the furnace', th ,preferable location of said outlet being indicated in dotted lines in Fig.

2. After startinga `hre in the furnace either upon the gratewith various kinds of-solid fuels or atthe `oil burner, the damper 14: is

closed',- it having -been opened for a shortA time to facilitate the starting of a re. Upon the y'closing of the damper all of the lheat generated within the furnace. or heater and all of thev products-of combustion are directed through the pipe 6.y To provide a Vmeans. for'fforcing the products of combustion andheat from the furnace so that it will extend to all parts of the orchard un- 1 fir/suitable pressure, a ed adjacent :to the therewith by a pipe 18 which is adapted to deliver the airv from the blower at a point near the grate and usually below the same. Any suitable motor, as for instance an electric motor Cliinaybe employed for operating the blower, a belt 20 being used to connect pulleys upon the said motor and blower. i i

The heated products` which pass from the furnace are forced landerithe action of the blower vto pass into themain 7 and from thence into the branch pipes 8. The piping 8 is usually provided with any other desire branches as 21 so that discharge outlets or nozzles may be located in as -many places as desired, throughoutY the plants or trees of the orchard. The pipes-8 and the similar branch ipes 21, are usually provided with upturne end portions, in which any desired blower 17 is mountfurnace Aand connected nozzles or distributing devices 22 may be mounted. A simple form of nozzle is shown as consisting of a 'perforated pipe sectionhas been necessary to ignite materials inA different burners or receptacles placed throughout the orchard, butthe time reuired in attending to all of these different evices frequently makes it possible for frost to injure portions of an orchard or garden long before heat can be distributed through the same, 0r at least any great portions thereof. By the present system a re built Within the' furnace, can be made to quickly and approximately at the same time, reach every ortion of extended plots of land upon w ich orchards may be spread.

What I claim is:

A smudgingv system for orchards, comprising a furnace having means for burning fuels therein, the said furnace having a smoke iue and a discharge pipea damper in the smoke flue for cutting oil the discharge therethrough, a blower adapted to deliver air under pressure .into said furnace, means for operating said blower, a main connected with said discharge pipe of the furnace tov receive and direct the heated products of 40 combustio'ntfrom vthe furnace, and branch piping extending vfrom the main and having discharge nozzles provided therein lfor delivering the Vsaid heated products among the trees of the orchard simultaneously.

In witness that I claim the foregoing I have hereunto subscribed my name this 26th day of Feb-,4912.
